Using DateTime as a one-liner in PHP

Question

A short and simple question which I couldn't really find an answer for.

In procedural PHP I could echo a date

echo date('Y-m-d'); ?>

In Object oriented PHP I have to use two lines

$now = new DateTime();
echo $now->format('Y-m-d');

Is it possible to do this in one line?

Answer 1

echo (new DateTime())->format('Y-m-d');

Answer 2

There are two options:

1. Create a DateTime instance using parenthesis and format the result:

   // requires PHP >= 5.4
   echo (new \DateTime())->format('Y-m-d');
   

2. You can use the date_create function:

   // date_create is similar to new DateTime()
   echo \date_create()->format('Y-m-d');
